In this study, the postembryonic development of the gonad in the Chinese Giant Salamander Andrias davidianus was observed using anatomical and histological techniques. The results showed that the original gonad appeared 28-49 days after hatching, and primordial follicles which were composed of oocyte and somatic cells began to appear in some gonads 133 to 175 days after hatching. Seminiferous lobule differentiated in some gonads 259-343 days after hatching. On day 427 after hatching, the ovary was composed of cortex with more primordial follicles and medulla with ovarian cavity; seminiferous lobules, cavity gap and testis interstitial tissue were present in the testis obviously. On day 511 after hatching, the testis was composed of seminiferous lobules and immature lobules. It was concluded that the post-embryonic differentiation of the original gonad in the Chinese Giant Salamander was similar to that of other anamniotes, and the gonad differentiation of the female occured earlier than that of the male.
